New OBD and BENCH protocols for Transtron 6XK1 and 4JXX – Isuzu heavy-duty vehicles.

OBD and BENCH modes make it possible to work on Transtron 6XK1 and Transtron 4JXX ECUs with two flexible and complementary workflows. OBD mode allows you to operate through the vehicle’s diagnostic port, while BENCH mode provides direct access to the ECU, making it particularly useful for repair operations and procedures that require greater operational control.

This update was developed to support daily work on trucks, buses and commercial transport vehicles equipped with a wide range of 3.0, 5.2, 7.8, 15.6 and 15.7 diesel engines, where operational continuity, reliability and fast intervention are essential.

Thanks to this new coverage, you can select the most suitable mode according to the vehicle’s condition and the workshop’s requirements, managing safe, accurate and repeatable procedures even on heavy-duty applications.
